I have noticed this for a while now.
While driving with the windows up, AC on or off, in 3rd gear, driving normal on the freeway, my car lets out a soft quiet Pfffffft.
It sounds like air escaping.
I get the car to 2500, and normally roll on to 2750, right in between it goes Pffffft.
I do have the by-pass mod :rollseyes that may or may not be part of it.
Does your car do this??
